This technique results in improved line regulation, enhanced load response characteristics, High power adjustable switching power supply (SMPS) 3 60V 40A High power adjustable switching power supply (SMPS) 3 60V 40A . This switching power supply was built because I needed a powerfull adjustable bench power supply. Linear topology would be unusable for this power (2400W = 2.4 kilowatts!), so I chose a switching topology of a two switch forward (half controlled bridge).
